Calculation of unit bale weight

Unit bale weight=bale density*bale size (M=p*V), bale size=bale length*width*height (V=L*W*H). Normally, the density of non-metal material is within 150-700kg/m3, while the density of metal bales is within 1500-5000kg/m3. There are quite considerate density differences among various material types.
